BOX STRUCTURE Filed Sept. 20, 1937 3 Sheets--SneeI 2 N. P. VAN WINGEN BOX STRUCTURE Filed Sept. 20, 1937 5 Sheets-Sheet 3 Inflllll:

stantialiy square ,fiaps`22 in alinement with which and between the same are relatively narrow flaps 23 outwardly beyond the scorings at I5.

With this blank construction the reinforcing flaps `I,I maybe bent inwardly against the inner sides of the ends 5, one overlapping the other as shown in Fig. 4 and the hand hole flaps at 1 bent inwardly through the openings at I3 and stapled in place as previously described. The end structure may be then bent upwardly about the scorings at 4 and the sides IB upwardly about the lower scorings 3, the flaps 20 turned inwardly toward each other to overlap the ends 5, as

shown in Fig. 2, whereupon said flaps 20 and the ends 5 with the reinforcing section II are stapled together. The flaps 22 are bent at rightangles to the flaps 2I and then the flaps 2I` and 23 turned at .right-angles to the plane of the top sections I9, the end flaps 22 coming inside of the end portions of the flaps 23 and being stapled thereto. This provides two top sections hinged to the sides I8 of the box at the scorings I4 and adapted to be turned inwardly, the slots at 6 and I2 in the end sections 5 and the end reinforcing members II receiving the inturned flaps 23 and the reinforcing corner portions 22 thereof, while the flaps 2| lie outside of the upper edge portions of the ends of the box (see Fig. 5).

With this construction of box the ends are very strongly reinforced. The holes through which the hands of those handling the boxes are inserted, at I3, are-strengthened and reinforced by the inturned and stapled flap sections "I, while the upper edges of said holes are rounded and broadened so as to make a smoother and wider bearing surface to come against the palms of the I bottom, this construction of box is one which is very easily reinforced by merely cutting a piece of paperboard stock to the right rectangular size and placing it within and against the upper side of the bottom of the box, lconnecting it in place if wanted; andn of course, either end or side flaps or both could be provided to the reinforcing bottom and stapled in place. However, such reinforcement is no part of the present invention and is mentioned only to show the adaptability of the box which I have invented to such reinforcement if it should be wanted.

The box structure is` one of an economical design, the blanks are cut with dies very rapidly, large quantity production may be had, the blanks may be shipped in flat form and very quickly and easily shaped into the completed box requiring only the stapling of the flaps 1, 20, and 22 after the blank has been bent along the scored lines to the proper positions.

The invention is defined in the appended claims and is to be considered comprehensive of all forms cf structure coming within their scope.

I claim:

1. A box comprising a bottom, vertical sides and ends, said ends having reinforcing members folded inwardly, one from each vertical edge thereof and overlapping each other and permanently connected to said en ds, and each side having projecting flaps extending inwardly over the endsand permanently secured thereto, as specified.

2. A construction containing the elements inv combination defined in claim 1, said ends having flaps cut therefrom at three sides and said reinforcing sections having openings' which are brought into conjunction when the reinforcing sections are folded into place, said flaps extend- 'ing through said openings and being bent around the upper edge portions thereof and against the inner side of the innermost reinforcing section, and means connecting said flaps, reinforcing sections and end members.

3. A box of the class described made from a single piece of paperboard having a horizontal bottom, vertical sides turned upwardly from the side edges of said bottom, vertical ends turned upwardly from the ends of said bottom, reinforcing sections one at each side edge of each vertical end and turned inwardly and overlapping each other at the inner side of each end, flaps extending from each end of each vertical side and overlapping said ends, and staples extending through said flaps, ends and reinforcing sections, as specified.

4. A construction containing the elements in combination defined in claim 3, said ends and reinforcing sections at their upper edges and intermediate their side edgeshaving vertical slots out downwardly therein for a short distance, said slots coming into alining conjunction when the reinforcing sections are folded one againsty the other and both at the inner sides of the ends.

5. A shipping case made from a blank of fiat material, having a bottom, two sides,7 and two top sections in alinement in said blank, and having ends one at each end of the bottom in alinement therewith and furtherA provided with reinforcing sections one at each edge of each end, said blank being scored transversely for its full width at each side edge of the bottom and scored longitudinally for its full length at each end of the bottom, said blank being cut starting at each point where said longitudinal and transverse scorings cross each other, said cut extending outwardly at an angle to the scorings for a short distance and then parallel to said longitudinal scorings whereby the blank may be folded upon said scorings to provide a bottom, vertical sides, vertical ends, inwardly foldable reinforcing sections, one at each vertical side edge of each-,end adapted to overlap each other and lie against theinner side of the end to which connected, and further providing an end flap one at each end of each vertical side adapted to be turned inwardly atthe outer side of each end of the box and extend vertically to the upper edges of the box, as specified.

6. A shipping case made from a blank of fiat material, having a bottom, two sides and two top sections in longitudinal alinement in said blank and having ends, one at each end of the bottom and further provided with reinforcing sections one at each edge of each end, said blank being scored transversely at each side edge of the bottom and scored longitudinally at each end of the bottom, said blank being cut starting at each point where said longitudinal and transversev scorings cross each other, said cuts extending outwardly at an angle to the scorings for a short distance and then parallel to said longitudinal scorings whereby the blank may be folded upon said scorings to provide the bottom, vertical sides, vertical ends and two inwardly foldable reinforcing sections for each end adapted to lie over each other against the inner side of the end fb scorings extending outwardly to the adjacent cut,

and said blank being further transversely scored a short distance inwardly from ach end thereof and having slots in each end of the blank in alinement with said longitudinal scorings extending to said last-mentioned transverse scorings. substantially as and for the purposes described.

7. A construction containing the elements in.

combination defined in claim 6, each of said ends and each of said end reinforcing sections having a slot in its outer edge substantially midway between its side edges, all of said slots in an end and two cooperating reinforcing sections coming .into alining conjunction when said reinforcing sections are inwardly folded to overlap each other and lie against the inner side oi' the end to which attached.

A box made from a blank oi dat material comprising, a bottom, vertical sides and ends, each end having reinforcing members integrally connected therewith and folded inwardly to overlap each other and lie against the inner side of its associated end, andl means integral with each vertical side adapted to be' folded inwardlyl toward each other at the outer sides of said ends whereby securing means may be passed through y said means and through the ends and said reinforcing members to permanently connect them together.

9. A box of the class described made from a .single blank of at material having a horizontal bottom, integrally connected vertical sides turned upwardly from the side edgesof said bottom, integrally connected vertical ends turned upwardly from the end edges of said bottom, reinforcing sections integrally connected, one at each vertical side edge of each end and turned inwardly and overlapping each other at the inner side of each end and aps integrally connected with and located one at each end of each of said sides, and turned inwardly toward each other over the outer sides of said ends, as and for the purposes specided.

10. A boxeomprising a bottom, vertical sides and ends, said ends having reinforcing members integral therewith and folded inwardly one at each vertical edge of each end and overlapping each other, and means for connecting the sides, ends and reinforcing members together.
